The above-mentioned configuration of Xi Drum 2 ’is attached to the armature coil 430 of the stator 40 0 and a driving force is generated due to the magnetic force, which drives the rotor 300 of the early phase disc-type commutatorless DC motor to rotate. For the purpose of step-by-step description, when a unidirectional current passes through the armature coil 430 of the printed circuit board 410, the armature coil 43 and the rotor magnet 31 will interact with each other and thereby drive the magnetic The rotor 300 of the rotor magnet 3 1 0 rotates. As shown in FIG. 9, a coil torque 600 is generated between the armature coil 430 and the rotor magnet 31. When the coil 430 passes through the central part of the rotor magnet 31 °, the coil torque is the largest; on the contrary, the more the torque is directed toward the ends of the magnetic pole, the smaller the torque, and finally the zero-torque stop state is reached. The position is usually called "dead point". The so-called cog effect is a means of resurrection that starts at the dead point by itself. The means for generating the toothing effect is a mechanism that applies a cogging force to the coil torsion force 600 to make the small torsion torque larger and the large torsion torque smaller, and makes the cogging torque 700 and the coil torsion 600 simultaneously. To produce the ideal synthetic torque 800 output. In other words, the cogging torque that has a load effect on the coil torque is inversely proportional to the coil torque to adjust the magnitude of the force, which promotes the stable and smooth operation of the motor. A number of proposals have been made on motors with this cogging function, such as in U.S. Patent Nos. 4 62 0 1 39, 4 7 5 7 2 2 2 and Japanese Patent Application Laid-Open No. 7-21 3 0 4 1. The purpose of these proposals is to produce coil torque waveforms of 60 Ω and produce cogging torque waveforms with a load of 700 for one balance to achieve the ideal composite torque.

Therefore, it seems necessary to apply the cogging effect at the position where the extraction torque becomes zero according to the rotor rotation direction. means. [Proposed problem to be solved] The above US patent cases 4620139 and 4757222 show the cogging effect as shown in Fig. 10 'wherein' the iron core 44 is placed on the fixture embedded yoke 420 in a connected or inserted manner and points Rotor magnet 31. In addition, there is still a different structure as shown in Figure 11. 'One of the fixtures has a fan-shaped notch on the disc yoke 4 2 0'. It seems to be designed to produce the cogging effect, but the means of generating this cogging effect 4 50 is inseparably related to the attachment position of the armature coil as a reference, so it is very difficult to set the correct position. In other words, before setting the cogging effect, the armature coil 4 3 0 is usually connected to the stator embedded vehicle 4 2 0, and then the armature coil 4 3 0 is used to find suitable settings one by one. The position where the cogging effect means is generated, and then the iron core 440 and the fan-shaped notch that cuts the stator inset yoke 420 can be fixed or inserted. It is only the setting of the position. In particular, a pair of armature coils 4 3 0 are respectively disposed at two corresponding positions on the top surface of the stator embedded yoke 4 2 0, and the other non-disposed parts will cause a large magnetic loss. At the same time, the formed The coil torque is also reduced, so that the expected driving torque cannot be obtained from the motor, which affects the running performance. On the other hand, Japanese Patent Application Laid-Open No. 7-213041 is shown in Fig. 12, which is based on setting a magnetic angle / 9 position (0 < 0 < π / 2) away from the dead point.

In particular, this magnetic body 46〇 is A bolt shape can be used to fix the printed circuit board 41 o and the holder yoke 420 at the same time. However, the function of the bolt is more practical than fixing the printed circuit board 410 and the stator-embedded yoke 420 as a means of cogging. Therefore, if the magnetic bolt is used to fix the printed circuit board 4100 and the stator embedded yoke 420, the gap between the magnetic bolt and the rotor magnet 3 10 may vary with the bolts, and the cogging torque generated by the magnetic bolt will also change. There are differences. Therefore, based on the difference in the bolt locking degree, the magnetic force between the bolt and the rotor magnet 3 110 will be different, and even the driving torque will be unstable. In particular, it is extremely difficult to place the bolt-type magnetic body 4 60 in a small motor. If it is necessary to adjust the lock levels, it is even more difficult. This method cannot be applied to micro motors at all. . The primary object of the present invention is to form a special-shaped armature coil that can maximize the effective coil torque on the stator embedded yoke, and then use the vertices of the armature coil as a reference, and use a plurality of cog effects according to a predetermined angle. A small projection is integrally formed on the stator embedded vehicle to provide a single-phase dish-type commutator-free DC motor that can generate ideal driving torque with a small current and has stable output. The second object of the present invention is to produce a simple change in the shape of the small projections by the cog effect to meet the multi-purpose torque requirements. A third object of the present invention is to ensure a stable and sufficient driving torque even if a small current is supplied. 【Improve methods】

Description of the invention (9) The side also has a certain radius of curvature, although in the radial direction of the axis of rotation-f is basically based on the principle of the width of the magnetic pole width of the rotor magnet 32. t: ancient: shown in Figure 7 The connecting sides of the vertices of the armature coil 43 are not indispensable even if they form a straight line. Discuss, the armature 3 series f rotor magnets 32 installed on the stator embedded yoke 42 magnetically interact with each other to output the coil torque, and generate a cogging effect to apply a load to the armature coil 43 The small protrusion 44 is an integral shaper. The cogging effect is generated by the small protrusions 44 based on the vertices of the armature line 圏 43. Starting from the reference point, move an arbitrary angle according to the rotation direction of the rotor magnet 32, but at a position that does not exceed a certain range, only Do not overlap with the armature coil 43. In other words, the angle at which the small protrusion 44 can be formed is equivalent to the width of one of the magnetic poles of the rotor magnet 32; that is, all the magnetic poles are 360 degrees in total, divided by the number of magnetic poles, which is 1/4. For example, 'when the rotor magnet 32 has 6 poles', then the angle assigned to each pole is 360 degrees / 6 = 60 degrees, whose 1/4 is equal to 15 degrees; that is, the position of the small protrusion 44 that produces the cogging effect should be Falling from the vertices of the armature coil 43, the place is moved forward by an angle of 15 degrees in the direction of rotation of the rotor magnet 32. Calculated according to this method, if the number of magnetic poles of the rotor magnet 3 2 is 8 ′ 1 0 or even 12 poles k ′, the setting positions of the small projections 4 4 for preventing the tooth effect from being generated are separated from the vertices of the electric coil 4 3 respectively. 11. 2 5 degrees, 9 degrees and 7.5 degrees. Secondly: the small protrusions 4 4 used to produce the cogging effect can also be used as shown in the fourth circle (a), (b) 'Cut the part of the plate-shaped anchor embedded yoke 42 and fold up From 'becoming closer to the rotor magnet 3 2; or mining

Description of the invention (10) Take another different on its upper surface. Furthermore, * turning degree, so instead of using 3 2 rotating force with the electronic magnet, _ and its occurrence forms one or a different kind of Syrup. The method is to use the mold to form a plurality of small ^ stators & system at 42 o'clock when the child is turning. Due to the angle of the dead point, a small protrusion that produces enemy teeth effects: Chengdu has a certain angle of the pivot coil 43. If the number 44 is set to only € 1 when it occurs with the armature coil 43 ... not to say, the point of turning zero torque is often 纟, the effect of the magnetically acting coil to twist the small protrusions may be an angle, so Only the same or similar effect that can be achieved by forming a plurality of small protrusions in response to each torque demand is shown in FIG. 5. The change in the shape of these small protrusions 44 can also promote the various torques of the teeth. Variety. This feature can change the polarity of the rotor magnet 3 2 according to different motor applications. That is, once the magnetic structure of the rotor magnet 32 is changed, the output of its coil torque will change accordingly. In order to make full use of the changed coil torque to obtain the ideal composite torque, the cogging torque must be matched. For adjustment, the simplest possible way is to change the shape of the small projections 4 4 for the cog effect. Figure 5 t 'The height b of the small protrusion 44 for the generation of the cogging effect determines the magnitude of the cogging torque', and its width a determines the electrical angle (the combined angle of the two magnetic poles on the rotor magnet); In particular, the width a ′ of the top end of the small projection 44 for generating the cogging effect can determine the degree of variation of the portion where the cogging torque is most varied. Therefore, if these can be moderately adjusted, it should not be difficult to generate cog force which can fully cope with the coil torque.

413976 五、發明說明（π) 上述追隨線圈扭力變化的嵌齒效應產生用小突塊44除 可在大小方面，即寬度a與高度b，改變以資應變外，亦可 選用不同材質使輸出的嵌齒扭力產生多樣性變化。所以， 如果能適當調整小突塊44的材質，當亦能同樣取得一與線 圈扭力形成最佳拍擋的嵌齒扭力，並進而獲得理想的合成 扭力輸出。 其次，如圖6所示，該電樞線圈4 3之各連結邊依轉軸 之半徑方向内彎較直線形狀為佳，再若其端部能與該轉子 磁石3 2之圓周形成内接形態則更佳。 根據佛萊銘的左手法則，因有效線圈扭力F = IL B，而 N、S極發生的磁力線垂直投射於線圈之半徑方向部分始能 產生有效推力，故線圈之有效長度L愈長則愈佳，線圈扭 力也愈大，從而亦得以相對降低電流消耗。 是以，頂點間連結邊呈直線時，其落在轉軸半徑方向 之有效長度K明顯不如連結邊呈内凹者落在轉軸半徑方向 之有效長度L。由於後者產生之線圈扭力較大，相對的電 流I可以減少，其能降低電流損失乃是一大剎點。 另一方面，形成於該固定子鼓制輥42之上的嵌齒效應 產生用小突塊44，若使其設於可接觸到該電樞線圈43之位 置，則可同時兼具導引電框線圈43固設之導塊功能，無需藉 助於其他治具即可將其安設於正確位置。如此，該電樞線 圈4 3已不至於四處溜動，亦便於利用接著劑將其黏貼於固 定子嵌制軛42之上的後續工作。 因而，非但不再需要往常使用的特殊治具，甚至組裝413976 V. Description of the invention (π) In addition to the small protrusions 44 for generating the cog effect following the changes in the coil torque, in addition to the size, that is, the width a and the height b, can be changed to meet the strain, different materials can be used to make the output Cog torque produces a variety of changes. Therefore, if the material of the small projection 44 can be adjusted appropriately, a cogging torque that forms the best clutter with the coil torque can also be obtained, and then an ideal composite torque output can be obtained. Secondly, as shown in FIG. 6, it is better that the connecting edges of the armature coil 43 are curved inward according to the radial direction of the rotation axis, and if the ends can form an inscribed shape with the circumference of the rotor magnet 32, Better. According to Fleming's left-hand rule, because the effective coil torque F = IL B, and the magnetic lines of force generated by the N and S poles are projected perpendicularly to the radial direction of the coil, effective thrust can be generated. Therefore, the longer the effective length L of the coil, the better. The larger the coil torque, the relatively low current consumption can be achieved. Therefore, when the connecting edge between the vertices is straight, the effective length K of the connecting edge falling in the radial direction of the rotating shaft is obviously not as good as the effective length L of the connecting edge falling in the radial direction of the rotating shaft. Due to the large coil torque generated by the latter, the relative current I can be reduced, which can reduce the current loss. On the other hand, the cog-effect generating small projection 44 formed on the stator drum-making roller 42 can be used as a guide motor at the same time if it is provided at a position where it can contact the armature coil 43. The function of the guide block fixed in the frame coil 43 can be set in the correct position without the help of other fixtures. In this way, the armature coil 43 can no longer slide around, and it is also convenient for the subsequent work of using the adhesive to adhere it to the stator embedded yoke 42. Therefore, it is not only no longer necessary to use special fixtures, or even assembly

The present invention is designed to make the armature coil as a closed loop 'and can greatly reduce the armature coil and the rotor to improve the motor. Torque and efficiency. Furthermore, by integrally forming the small protrusions for exerting the cogging effect on the fixture-embedded yoke, the formation of the small protrusions can be shortened. 1 Secondly, the change in size or shape of the small bumps due to the cogging effect is more self-amplifying, and it is easier to change the magnet structure of the rotor according to the application of the motor or the rotor. ▲ In particular, the cog effect is completed at the same time as the production of the fixture inlay yoke, which produces small projections, which is very beneficial for mass production; in addition, the cogging effect is reduced in advance in Gu Zhizi. The protruding block has a guiding and temporary holding function when the armature coil is subsequently installed, which facilitates the simple and correct placement of the armature coil on the stator embedded yoke to increase the productivity.
